Fast path for Dictionary -> View cast for large types & cross cast

[Jefffrey]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

See original issue comment: https://github.com/apache/arrow-rs/pull/8912/changes#r2553987033

Describe the solution you'd like

Implement fast paths for casting from LargeUtf8/LargeBinary to Utf8View/BinaryView -> need to consider if offsets fit

Implement fast path for casting Utf8 -> BinaryView, Binary -> Utf8View -> need to consider if need to validate binary data for Binary -> Utf8View case

See:

arrow-rs/arrow-cast/src/cast/dictionary.rs

Lines 37 to 49 in 08dcc0b

	// `unpack_dictionary` can handle Utf8View/BinaryView types, but incurs unnecessary data
	// copy of the value buffer. Fast path which avoids copying underlying values buffer.
	// TODO: handle LargeUtf8/LargeBinary -> View (need to check offsets can fit)
	// TODO: handle cross types (String -> BinaryView, Binary -> StringView)
	// (need to validate utf8?)
	(Utf8, Utf8View) => view_from_dict_values::<K, Utf8Type, StringViewType>(
	array.keys(),
	array.values().as_string::<i32>(),
	),
	(Binary, BinaryView) => view_from_dict_values::<K, BinaryType, BinaryViewType>(
	array.keys(),
	array.values().as_binary::<i32>(),
	),
